7 Claims.

This invention relates to printing mechanism for tabulating machines or the like and is primarily directed to the provision of means for selectively feeding classified record sheets to a printing device for receiving data of arelated classification.

One object of the invention is to provide improved comparing mechanism for comparing classification data on a record sheet or bill with classification. data on a controlling record card and for automatically initiating printing operations under controlof other data on the card.

The comparing mechanism includes an entry receiving and retaining device which is adapted to receive an entry from a record card during a tabulating cycle of operations. During a subsequent total taking and resetting cycle of operations data are read from the record bill and a comparison made between this data and the data in the entry receiving device.

agreement, the device is immediately reset and tabulating operations take place during which entries are made on the bill in accordancewith perforations in the record card. Automatic group control devices are employed to permit a series of entries to be made on the bill from a series of related cards comprising a group.

-A further object of the invention resides in the provision of separate control or comparing devices, one to determine the relationship be tween the bill and the leading card of a group, and the other to determine the relationship between the cards comprising the group. This arrangement lends flexibility to the machine and widens the scope of its practical application.

A still further object is to provide a visible indication of an improved nature whereby upon interruption in machine operation, the operator the card and bill in operative position and deterof construction and combination of parts hereinafter set forth and claimed.

. Fig. 18 is a diagrammatic showing of a group of cards.

In order that the detail description may be 0 ber of bills to be prepared is of considerable volume and it is a-desideratum to have them completely prepared aslsoonrafter -the acquisition of thec'ontrollingdata as possible, the: bills are addressed sometime previous so that when all the necessary data have been- ;collected it remains but to enterthea charges and other: items. Preprinted and prepunched bill formsare made use of which may consist of several sections such as, the bill proper, thegcashierscoupon, the collection coupon and a tabulating card. Figs. 11

and 12 show such a -form,; it ;being understood that-Fig. 12 is integral withand forms-a contlnuation of Fig..1l before severance; The sectionsare each printed with a serial number for example 4740 which number is also prepunched in the cashiers coupon and in the Serial No. field of the card (Fig. 12). These perforations are made in accordance with the well known Hollerith system of indicating numerical values in vertically spaced index point positions.

The forms are then addressed in each section as shown and the card portions severed. The remainder of the bill is then set aside until the advent of the billing period. The card (Fig. 12) may then be perforated with pertinent information relating to one type of service. The customers permanent account number for example 7402 is also perforated in the Acct. No. field. For each other type of service to be charged against the customers account, a separate card similar to Fig. 12 is prepared in which the customers account number is perforated but which does not have the serial number. In the instant example, there will be four tabulating cards for the same account, 7402 viz. a Gas card, a Sundries card, a Mdse card and an "Electric" card. The Gas card which contains the serial number punching is placed at the head of the group and is the first card of the group to be fed through the machine.

At the commencement of billing operations, then, there will be a set of serially numbered and arranged, addressed bills in their original order and a set of cards comprising groups of one or more cards relating to the several accounts. The groups of cards have been sorted into the same order as the bills and the card having the serial number leads its account number group.

In Fig. 18 is shown diagrammatically a group of cards and a related bill. As explained, the first card, which was originally attached to the bill, contains the Serial No. 4740" by means of which the card is later identified as belonging to the similarly numbered bill. 'A further, separate card is made out for each additional item for which the customer is to be billed. These further cards bear no relation to any bills and in order to provide identification, all the cards, including the first, are perforated in accordance with the customers "Account No. 7402." Thus through the Account No. 7402" all the cards of Fig. 18 are identified as belonging to the same customer and through comparison of the Serial No. 4740" of the first card with the Serial No. 4740" of the bill, the correct relationship is secured to bring about listing of the items of all the cards on the one bill. It is, of course, apparent that the number of cards related to any bill varies according to the number of items to be billed, so that if but a single item is billed, there will be but the bill and the first card.

General operation 0/ tabulatino machine The tabulating machine to which the improvements of the present invention are especially adapted may be of the type disclosed in Patent No. 1,762,145 granted to G. F. Daly and R. E. Page on June 10, 1930. The operation of the machine in the performance of functions which are similar to those of said patent and which are necessary to an understanding of the invention will first be briefly outlined after which the improvements will be explained in greater detail.

Figs. 16 and 16a illustrate the wiring of the complete machine. During listing and adding operations the machine is driven by a tabulating motor I'M controlled by a group of cm and relay controlled circuits to be traced later and during total taking operations the machine is driven by a reset motor RM controlled in a manner to be explained. When the tabulating motor TM is in operation, the tabulating c'ards bearing differentially arranged index points representing digits are fed first beneath the upper analyzing brushes UB and exactly one machine cycle later beneath the lower analyzing brushes LB. Figs. 13, 14, and

15 show the card feeding rollers and brushes U13 and LB diagrammatically.

As the cards pass the lower brushes, perforations in the index point positions will instantaneously close circuits through the proper lower analyzing brushes LB to energize counter magnets lll (Fig. 160) or printer magnets H or both together.

As usual the timed energizations of these magnets control mechanism for entering the data corresponding to the card reading on the counter wheels or for stopping the type bar at the corresponding printing position. These functions do not enter specifically into the present invention and will not be described in detail as they are well understood and fully explained in the patent referred to. For greater flexibility, the entering circuit arrangements have been altered so that data may be added in any counter position and printed in any printer position. A representative adding circuit traced as follows will make this clear. In Figs. 16 and 16a the common conductor I! for the brushes LB is connected to the right side of line It through the usual control devices and upon the arrival of a perforation at the brush station current will flow from common If (Fig. 16a), hole in the card, brush LB,.plug connection l4, adding magnet I0, contacts I5, wire it to left side of line ll. 11' printing is desired, a plug connection ll is made between brush LB and a pair of normally closed contacts I. A circuit is then traceable from common i2, brush LB, connection ll, contacts I, printing magnet ll, wire 20 to left side of line H.

During total taking operations, printing is controlled by the usual stepped cams 2i and contacts 22 which latter may be connected by a suitable plug connection 23 to normally open contacts 24 associated with a selected printing magnet ll. During total taking operations a magnet 25 is energized, in a mannerto be explained later, to cause closure of contacts 24 and opening of contacts IS. A total printing circuit is thereupon traceable from line I1, wire 20, printing magnet I I, contacts l4, connection 23, contacts 22 (whose time of closure is in accordance with the amount contained in the adding wheel), contacts 2| (closed by magnet 21) during total taking operations, wire 2| to mm side of line I: through m usual control contacts and switches.

The usual automatic control unit is also provided to cause the machine to either stop or automatically enter upon total taking operations when the group numbers which in the present case are the Account" numbers relating to particular customers of successively fed cards fail to agree. This unit is the some as heretofore employed in machines and requires no detailed description. Briefly, one of the magnets 29 (Fig. 16) is plug connected in series between the upper and lower brushes of each column selected for automatic control as by plug connections II and the contacts ll of the selected magnets are connectcd in series with each other in the control circuit which will be traced presently. When the control perforations in the cards under the upper and lower brushes agree, the selected magnets 2| will be energized momentarily and their contacts Ill) 39 closed. The contacts when once closed, will remain so until the end of the machine cycle and then open.

The minor control circuit is traceable as follows: from line I1, wire 32, minor relay points 33a, minor relay 33, wire 34, series contacts 39, upper card lever contacts UCLI to right side of line I3. If one of the contacts selected fails to close, this circuit is interrupted and causes deenergization of relay 33 which thus permits closure of its points 33b. A circuit is then established from line I1, wire 32, points 33b, wire 35, reset control relay 36, motor control relay 31 to line I3. The relays open their respective points 39a and 31a, the latter functioning to break the tabulating motor circuit. Contacts T4 serve to hold relay 33 energized while contacts 39 are being set under card control.

The above sets forth in brief the usual operations of the tabulating machine to which the present improvements are applied.

Serial number indicator Figs. 6 and 'i show the indicator mechanism which has been applied to a tabulating machine and which is adapted to receive and retain the serial number as punched in the first card of,"

each group.

The general construction is similar to that of the accumulators, energization of a magnet 39 causing coupling of indicating wheel 39 to the continually running counter drive shaft 39a. Wheel 39 is thereby turned an amount proportional to the value of the index point perforation sensed. Connected to wheel 39 by means of gearing 49 is a pair of electrically connected brushes 4| which are carried by and insulated from the uppermost gear 49. The brushes cooperate with a. plurality of conducting segments 42 and a common arcuate conducting strip 43. The relationship is such that with wheel 39 positioned to represent a particular number, one of the brushes 4| will be in contact with the correspondingly numbered segment 42 and the second brush will be in contact with strip 43. After the serial number of a card has been set up on this device, a comparison is made with the serial number of the bill, as will be hereinafter explained, following which the device is reset to zero. The resetting is effected in the same manner as for the usual counters. Magnet 44, upon energlzation during a total taking and resetting cycle, is adapted to cause coupling of the resetting gear 45 of the device with,shaft 49 which rotates during such cycles. This action zeroizes the device in the same manner as the usual counter wheels.

Bill feeding mechanism The bill feeding mechanism is shown in Figs. 1, 4, and 5 and is controlled from the total shaft 41 of the machine which is adapted to make one revolution during a total taking and resetting operation of the machine. Bills, prepunched with the serial number are placed in the supply hopper 49 from which they are fed singly by a picker knife 49 mounted for reciprocation in the frame of the machine. An operating arm 59 is secured to a shaft 5| which carries an arm 52 at one extremity (Fig. 1). Arm 52 is connected by a link 53 to a bell crank 54 pivoted at 55 and having a follower roller in engagement with a box cam 59 carried by a shaft 51.

Integral with cam is a bevel gear 59 meshing with a bevel gear 59 on one end of an oblique shaft 99 whose lower end has a bevel gear 6| in,

, mesh wlth a bevel gear 62 rotatable on a, stud 93. Secured to gear 62 is a toothed mem r 94 which is adapted to be intermittently driven by a toothed member 95 carried by the total shaft 41. The ratio of the drive is such that during the first half revolution member 65 causes cam 59 to make a full turn and reciprocate picker knife 49 once to feed a bill to feed rollers 69 which convey it past analyzing brushes 61 and a so-called card lever brush 99 (Fig. 5) and then to feed rollers 69 which advance it into engagement with feed rollers 19. Rollers 66 and 69 are driven by a gear 1| on shaft 51 which'meshes with pinions 12 and 13 on thel'ower shafts of rollers 66 and 69 respectively. Also driven by gear 1| is a gear 14 (Fig. 3) which carries, insulated therefrom, a pair of electrically connected brushes 15 of which one cooperates with an arcuate conducting strip 16 and the other with a column of segments 11. Brushes 15 successively connect the segments 11 and strip 19 as the corresponding index point positions of the bill are sensed by brushes 91. It may be stated here that the bills are placed face down in the hopper 49 and that they are fed with their top edges first so that the index point positions pass brushes 91 in the order 0--1-234--5--6799. The manner in which segments 11 cooperate electrically with brushes 61 will be explained in connection with the wiring diagram.

Further advance of the billls effected during the second half revolution of shaft 41 through the action of crank arm 19 as it rocks through of arm 19, link 19, connected thereto, rocked an arm 99, connected at its upper end, in a counterclockwise direction.

Referring to. Figs. 8 and 9, arm 99 is attached to a cam member ill to which is secured a disk 92 which is provided with spring supporting pins 93. Springs 94 urge friction rollers 95 between the cammlng portions of member 9| and the inner periphery of a drum 96 which is mounted for rotation about a stud 91. A spring pressed friction shoe 99 tends to restrain movement of drum 99. With the above construction it is apparent that during the counterclockwise movement of arm99, cam member 9|, plate 92 and rollers 95 turn in the same direction without-disturbing drum 96. On the return stroke of arm 99, however, rollers 95 are wedged between the cam surfaces of member 9| and drum 96, causing the latter to move therewith in a clockwise direction.

Drum 99 is provided witlfteeth 99 which mesh with a pinion 99, secured to a gear 9|. Gear 9| through pinions 92 drives feed rollers 19 and 93 and through a gear 94 drives the printing platen 99 so that the bill isadvanced around the platen a distance sufficient to bring the first line of the bill into printing position.

From this position the bill is advanced step by step as items are listed thereon, by means of the usual spacing devices, shown in Fig. 10 where 99 represents the printing cross-head operating shaft which is oscillated once for each operation of the printing mechanism. An arm 91 carried by shaft 96 rocks a structure 99 pivoted at 99 and which has link connection i99'with platen pawl operating arm |9|.

During the second half of the subsequent total taking cycle the bill is advanced by the platen and rollers I92 through guides I93 to a position where the leading edge ,of the bill lies within the open jawsof stacker clips I94. The stacker is (ill of conventional structure, driven as shown in Fig. 1 by sprocket and chain connection I05 from shaft 51 during the first half of the total taking cycle, so that it is not until the next succeeding total taking cycle that clips I04 close on the leading edge of the bill and swing it around into stacker I06. A fixed roller I01 engages clip I04 to open the same against the tension of its spring as it passes through the bill receiving position.

Wiring diagram The complete operation of the machine will now be described in connection with the wiring diagram (Figs. 16 and 16a) with particular reference to the preparation of a bill as in Fig. 11 under control of a group of cards of which the card in Fig. 12 is the leading card. With the tabulating cards placed in the feed hopper of a tabulator of the type disclosed in Patent No. 1,762,145, and the bills placed in the hopper 48 of the machine disclosed in this application the start key ST is depressed to close pairs of contacts STI and STZ (see Fig. 16). Previously to this,switches I08, I09, and H will have been closed to provide for the continuous automatic operation of the machine. Closure of contacts STI will prepare the minor control circuit for operation.

In previous machines of this type it has been customary to send the machine through a resetting cycle of operations during which the minor control circuit was set up. In the present machine, however, this setting up is taken care of by the closure of contacts STI concurrently with the usual starting operation of the machine. Closure of contacts STI will complete a circuit from line I1, switch I08, lower card lever contacts LCL3, contacts STI, wire III, minor relay 33, contacts UCL3, LCL2 and wire II2 to right side of line I3. Relay 33 thus energized will attract its armature which will complete the usual holding circuit for the relay which will thereupon remain energized until the occurrence of a group number change.

Concurrently with this operation, the closure of contacts ST2 will complete the usual tabulating motor circuit to commence feeding cards. This circuit is traceable from line H, motor TM, motor relay II 4, tabulating clutch magnet II5, start relay II Ii, relay points II3a, start key contacts STZ, relay points 31a now closed, stop key contacts S, cam contacts P3, to line I3.

A cycle of operations of the tabulator will be thus initiated during which the first card is advanced by the picker to the upper brushes and at the end of this cycle the first card will have its leading edge at the upper brushes UB as indicated diagrammatically in Fig. 13.

The continued depression of the start key will send the machine through a second cycle during which the upper card lever contacts are open and at the end of which the lower card lever contacts LCL3 open to interrupt the circuit through contacts STI. During this cycle the serial number on the leading card of the group is analyzed by the upper. brushes and the number is entered into the indicating counter through circuits of which the following is representative: from line IT, cam contacts T2, upper brush common I20, perforation in the serial number field of the card, upper brush UB, plug connection I2I, indicating counter magnet 38, break contacts 38a, wire I22, to right side of line I3. In this manner, the serial number is entered into the several orders of the counter as the card passes the upper brushes UB. It will, of course, be understood that the remaining cards in the same group have no perforations in the serial number field so that as these other cards pass the brushes during subsequent cycles, no entries will be made into the indicating counter.

At the end of the second cycle, the cards will have been advanced to the position diagrammatically indicated in Fig. 14 with the first card at the lower brushes and the second card at the upper brushes. Also during the same cycle, the usual automatic control mechanism will have functioned to automatically initiate a total taking and reset cycle of operations upon closure of contacts LI (Fig. 16). The circuit is traceable from line I3, contacts P3, contacts S, switch IIO, contacts LI, wire I23, contacts IIa, reset clutch magnet I24, multi-contact relay 25, motor RM, to line H.

During this cycle the first bill will be advanced to the position indicated in Fig. 14, in which position the leading edge of the bill is between the brushes 5! and the common bar BIa and the card lever brush 58 is thereby insulated from the common bar. rest and can only be restarted by depression of the reset key R (Fig. 16). In this manner the proper sequence of feeding operations is preserved and is brought about under control of the following circuit completed under control of cam contacts I25, which closed during the previous reset cycle (see Fig. 17). The circuit may be traced from line H, contacts I25, wire I25,

relay magnets I21 and I28, wire I29, relay points Ia, wire I3I, to right side of line I3. Relay points I30a are normally closed and open only when a comparison is made between the bill and the setting on the indicator, as will hereinafter be explained.

Energization of relay I 21 will cause closure of its points I2Ia, setting up a further circuit from line I1, cam contacts I32, relay I33, wire I34, relay points I2Ia, wire I35, relay coil I36, relay coil I I3, upper card lever contacts UCL4, wire I31, to line I3. Contacts I32 remain closed during subsequent tabulating operations (see Fig. 17) and relay I33, through its contacts I33a, provides a holding circuit to keep relay magnets H3 and I36 energized. The former will therefore hold its points 311 open. These points,

as previously explained, are in the manual and automatic starting circuits of the tabulator so that resumption of operation of the tabulator by these devices is prevented.

Closure of points I35a will permit the initlation of a reset cycle of operations upon closure of reset contacts R. This circuit is traceable as follows: from line I3, contacts L2, reset contacts R, relay points I36a, wire I 23, through the reset clutch magnet I24 and motor RM to left side of line, as traced above.

During this second reset cycle the bill is advanced from the position in Fig. 14 to the position in Fig. 15 where the first line to receive printing is at the printing position, During the first half of the cycle the perforations in the serial number field of the bill are analyzed by the brushes 0! and as they are analyzed, a comparison is made between these perforations and the data previously entered into the indicating counter under control of the serial number perforations in the first card. This comparing mechanism includes the emitter generally designated E in Fig. 16 whose brushes 15 successlvely connect the segments 11 with the common The machine then comes to u strip I. in the order 0, 1, 2, 3, 4, etc. in synchronism with the analysis of the corresponding index point positions on the bill by the analyzing brus: es 61. If the setting of the counter corresponds with the number on the bill, the circuits will be completed through the brushes 61 and the emitter E of which the following is represer ative: Assuming the brush ll of the readout device farthest to the right to be set at "4". a circuit would be completed when brush iii of emitter E reaches the 4" segment as follows: from line H, wire I", relay points Ilia wire 0, common strip 18, brushes It, the "4 segment 11, wire lll4 of a group of wires generally designated Ill, wire Ill-,4, 4" segment 42, brushes II, common strip 43, relay magnet I30, brush 61, perforation in the "4" index point position of the bill, common 81a, to right side of line ll.

Energization of relay I80 will open its points "0a and close its points lllb whereby the latter will complete a circuit from line it, wire ill, relay points "0b. holding coil I", wire I, cam contacts I25, which are closed during the reset cycle, to line 11.

If all the perforations in the bill are in agreement with the setting of the indicating counter,

\ the several relays I will be energized at times corresponding to the value of the setting in their respective positions and at the end of the reset cycle, all of the contact points 1 Illa will be open so that no current path is provided for the circult, above traced, through relays i2! and I28. Consequently, at the beginning of the second half of the reset cycle, contact points Illa will be closed and cam contacts I, closing at this time (see Fig. 17), will complete a circuit from line ll, cam contacts I", indicating counter reset magnet 44, relay points lilo, wire ill, to line I]. As explained, magnet 44 will couple the indicating counter to the resetting shaft so that during the second half of the reset cycle, the counter will be zeroized.

At the end of this reset cycle, the cards and bills will occupy the positions diagrammatically indicated in Fig. 15, where the first card is about to traverse the lower brushes LB and the first bill is in position to receive the first printing impression. A second card is about to pass the upper brushes and a second bill is in position beneath-the brushes '1.

Toward the end of the reset cycle, the cam contacts P2 close and complete the usual automatic starting circuit whereupon card feeding operations will resume and printing will take place on successive lines of the bill under control of the lower brushes.

account number fields on the two cards are being compared and the change in account number sensed by the automatic control mechanism. The machine will thereupon, under control of the automatic control mechanism, enter upon a total taking and reset cycle of operations, during the This automatic starting circuit is traceable from line il, motor TM, relay first half of which the total is printed on the bill in printing position and also during the first half of which a new bill is advanced past the brushes 61 and a comparison is made at such time with the data set up in the indicating counter. During the second half of the reset cycle, the new bill is advanced to printing position and the previous bill is advanced into engagement with the Jaws of the stacker. If the comparing operation discloses an agreement between the bill and the indicating counter, the latter is conditioned for resetting during the second half of the cycle. If. however, there is a disagreement, the machine will stop, due to the interruption of the automatic start circuit by the opening of relay points 3a, as explained, and the indicating counter will not be reset. next group will be visible on the wheels of the indicating counter and the printed serial numbers of the bill which has been compared with the counter setting and of the last bill printed will also be visible in the bill feeding section so that the operator can determine the reason for tho stopping of the machine. I

If it is found upon inspection that a bill is present for which there are no record cards, this bill is removed by sending the machine through another reset cycle, which may be initiated by Inspection of the scribed. Such devices have the same reference characters as the devices shown in Fig. 1 of Patent No. 2,056,395, issued to Garman et al. on October 6, 1936 and to which they correspond. These include contacts L4, L3, L5, UCL2, LCLI, T3, UCLI, LCM, etc.

When the machine stops because of non-comparison and the operator finds upon inspection of the serial numbers on the indicator and bill. that the bill is out of place and should be removed, it is simply necessary to depress the reset 'key to close contacts R (Fig. 16). This, as is apparent, will send the machine through a total taking cycle during which the next bill is advanced and compared with the retained setting of the'indicating counter. If this next bill is also not in agreement, the machine will stop again without resetting the counter. oral bills should be passed before agreement can be reached the operator may hold the reset key depressed in which event a succession of total taking cycles will ensue until the proper bill is reached whereupon the counter will automatically reset and card feeding and analyzing will automatically resume to accumulate data from the next group of cards which relate to the agreeing bill.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing fromthe spirit of the invention.
